Questions
Is there a KiCad symbol and footprint for the PCA9502BS?
Yes. The symbol is agg-kicad:PCA9502 and the footprint agg:HVQFN24-NXP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PCA9502BS?
HVQFN-24-EP(4x4), with 25 pins. Its footprint is drawn on this page.
Where is the PCA9502BS datasheet?
NXP Semiconductors publishes it: the Datasheet link on this page opens it.
Where can I order the PCA9502BS?
JLCPCB lists it as part C2669722, with 3 in stock; the sellers' links on this page open their listings.
What can replace the PCA9502BS?
Parts like it in the library: the PCA9555PW by NXP Semiconductors, the AW9523BTQR by AWINIC, the TCA6416ARTWR by Texas Instruments and the TCA9535PW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
